AUTOMATIC HUMIDIFIE'R FOR WARM-AIR FURNACES.

This invention relates generally to autoof liquid into the casing. Asshown one end matic humidifiers for warm air funaces and of the needlevalve is slotted at 1 1 for en 5 consists of certain novel features ofconclosing an end of the plate 12 and is prostruction, combinations andarrangement of vlded with a'transverse opening 15 register- 5 parts aswill be more fully described and ing' with an opening 16 in the plate.These particularly pointed out in the appended openings are adapted toreceive a cotter pin h 17 for pivotally mounting the needle valve In thedrawings: to the plate.

This post is also provided with alike characters of reference designate like transverse opening 20registering with an parts, the numeral lindicates a humidifier opening21 in the plate 12. casing made in accordance with the presentHeretofore it has been the practice to invention, 2 the valve thereforand 3 .the pr d a co e piirsimilar 0 t pin 17 float for operating thevalve. In practic for plvotallyconnecting the plate 12 to the 20 it hasbeen found that it is verydesirable post 18. However, as statedaforesaid beto have the casing 1 of as small a ar a a cause of thelimited area within the casing 1 is practically possible. Therefore, asilgreatdifiiculty has been encountered in relustrated, one end of thecasing designated 111 v1ng and inserting thepin, as practically t 4 i dl large ugh t eeeemno roon'r is provided for the manipulation 25 modatethe float and the side walls 5 of of a pin removing tool.

It will he noted that the extreme lower portion of the plate 12 ex ondedto form n projection 9:3 which is adopted to abut :ieoinst the post l5Lt'or liinitiiig the down Word movement of the ilout end flout rod. Thearrangement such that even in the lowest position of the ilout red thepoint oi? the valve is not withdrawn from tho surjfuee oil the valvesent. it will theretore he uppurent that while on adequate u piveid anddownward llOVLlllClll o l the velvo is ulloived tor the o'llieientoperation thereof, the vulve is always guided in its opening and closingnujrveinent because of this arrangement.

It is very important in assembling the valve and the o1 'np' thut it beplaced in as near true vertical position as possible. 'llherolore tofacilitate the correet por' lLiUl. hip of the valve, the end wall ('3pro vided with vertical shoulders do which. are positioned in such anuuiner thut the dist-inure between them is slightly less than thedinineter of the heeded portion or nut o.

This will always insure it tight lit und preventany looseness oi the nut in the ensing and thereby provide for thecorrect vertical position of the valve.

\Vhile it is believed that from the foregoing description, the natureand advantage or. in invention will be readily understood, I desire tohave it nnrlerstood, that I do not limit myself to the speeiiioconstriwtion shown and (.leserihed end that snoh changes lnrqv heresorted to when desired us full \vithin the scope of the claims.
